Zovo Inflation Calculator
Adjust US dollar amounts with the published CPI-U index, and download a year-by-year table.
Zovo Inflation Calculator turns an amount of US dollars in one month or year into its value in another, using the published Consumer Price Index for All Urban Consumers (CPI-U, series CUUR0000SA0, 1982-84=100). It reports the adjusted amount, the two index values, the cumulative inflation, the average annual rate, and the change in buying power, and it builds a year-by-year table of the annual CPI average and yearly inflation with a CSV download.
What it does
- Adjust an amount between two years or between two months with the published CPI-U index
- Cumulative inflation, average annual rate, and buying-power change
- Year-by-year table of the annual average CPI and the yearly inflation rate
- CSV download of the table
- Index values are used in whole thousandths and rounded half-even
- Published CPI-U data bundled with its source URL and retrieval date
